Heterologous expression and characterization of a new galactose-binding lectin from Bauhinia forficata with antiproliferative activity.

Summary of "Heterologous expression and characterization of a new galactose-binding lectin from Bauhinia forficata with antiproliferative activity."

In this study, we describe the characterization of a new lectin, BfL-II, purified from the seeds of Bauhinia forficata, which is distinct, at sequence-level, from the previously reported lectin from the same specie (BfL). In addition, the gene for this lectin was cloned and expressed in Escherichia coli and its antiproliferative activity was evaluated against human breast and colorectal cancer cells (MCF-7 and HT-29, respectively). The treatment with 100 μg/μL of either native or recombinant BfL (nBfL or rBfL) significantly reduced the proliferation of both cancer cell lines (p < 0.01). The inhibition of HT-29 cell proliferation was as high as 82.5% and 93.6% with 100 μg/μL of rBfL-I and nBfL after 24 h, respectively. Therefore, BfL-II presents a promising antiproliferative activity, which may be applied in the development of new anticancer treatments.

Medical and Biotech [MESH] Definitions

A specific mannose-binding member of the collectin family of lectins. It binds to carbohydrate groups on invading pathogens and plays a key role in the MANNOSE-BINDING LECTIN COMPLEMENT PATHWAY.

A sialic acid binding lectin that was originally identified as an adhesion molecule for inflammatory MACROPHAGES and activated MONOCYTES. This protein is the largest known siglec subtype and contains 16 immunoglobulin C2-set domains. It plays a role in cell to cell interactions and interactions with BACTERIA.

Stucturally-related receptors that are typically found on NATURAL KILLER CELLS. They are considered lectin-like proteins in that they share sequence homology with the carbohydrate binding domains of C-TYPE LECTINS. They differ from classical C-type lectins, however, in that they appear to lack CALCIUM-binding domains.

Complement activation triggered by the interaction of microbial POLYSACCHARIDES with serum MANNOSE-BINDING LECTIN resulting in the activation of MANNOSE-BINDING PROTEIN-ASSOCIATED SERINE PROTEASES. As in the classical pathway, MASPs cleave COMPLEMENT C4 and COMPLEMENT C2 to form C3 CONVERTASE (C4B2A) and the subsequent C5 CONVERTASE (C4B2A3B) leading to cleavage of COMPLEMENT C5 and assembly of COMPLEMENT MEMBRANE ATTACK COMPLEX.

Diffusible gene products that act on homologous or heterologous molecules of viral or cellular DNA to regulate the expression of proteins.
